:warning: Please refresh the page if the CCF ranks don't show up on Connected Papers .

CCFrank on Web of Science

CCFrank on Semantic Scholar

Install

Directly install from the Chrome, Firefox or Microsoft Edge Add-ons Store (Recommended) or load from the source.

Install from the Chrome / Firefox / Microsoft Edge Add-ons Store

Find the CCFrank extension in Chrome Web Store / Firefox Bowser Add-ons / Microsoft Edge Add-ons Store .
Click the Add to Browser button.
CCFrank needs to read and change dblp, Google Scholar, Connected Papers and its mirror sites. To approve, click Add extension.

Load Unpacked

Clone CCFrank to a directory.

Open the Extension Management page by navigating to chrome://extensions.
- The Extension Management page can also be opened by clicking on the Chrome menu, hovering over More Tools then selecting Extensions.
Enable Developer Mode by clicking the toggle switch next to Developer mode.
Click the LOAD UNPACKED button and select the directory holding CCFrank.

MCP Server

CCFrank can also run as a local stdio MCP server without changing the browser extension code path.

The MCP server exposes one tool:

ccf_rank

Input:

{
  "query": "SIGCOMM"
}

Output fields:

matched
rank
canonicalName
venueType
matchedBy
normalizedQuery
sourceKey

Supported input forms:

Full venue name, e.g. ACM Transactions on Computer Systems
Abbreviation, e.g. SIGCOMM
DBLP URL/path, e.g. https://dblp.org/db/conf/sc/index.html

Start the local MCP server:

node ./mcp/server.js

npm run mcp

npx -y ccfrank-mcp

Install in Codex

codex mcp add ccfrank -- npx -y ccfrank-mcp

Install in opencode

Add the following local MCP entry to your opencode config:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "ccfrank": {
      "type": "local",
      "enabled": true,
      "command": ["npx", "-y", "ccfrank-mcp"]
    }
  }
}

Install in OpenClaw

OpenClaw's ACP bridge does not support per-session mcpServers. Configure this repository as a local MCP server on the OpenClaw gateway or agent side instead, and point that entry to:

command: npx
args:
  - -y
  - ccfrank-mcp

Notes

The MCP server reuses the repository's embedded CCF data and does not perform network lookups.
The browser extension behavior, manifest, and content-script entrypoints are unchanged.
